Examining the Level of Information Literacy among First-Year English Majors at the University of Sargodha

The main goal of this study was to look into the information literacy (skills and standards) of English Language majors at Sargodha University. A total of 160 undergraduates, both men, and women, took part in the research. To get to their end goal, researchers had to fill out a questionnaire created by Mittermeyer and Quirion (2003). The results of this study showed that undergraduates at UOS don\u27t know enough about how to use information. Because of this outcome, it was suggested that students from UOS take part in the research

Laboratory Testing to Evaluate the Effectiveness of Caprocks for CO2 Storage

The increased anthropogenic emission of carbon dioxide (CO2) is a serious concern due to its effects on global climate change. Capture of CO2 from point sources and storage in the porous rocks of deep saline reservoirs is considered a practical choice for reducing CO2 emissions into the atmosphere. A fundamental necessity for long-term storage of CO2 in saline reservoirs is the integrity of non-permeable rock called the caprock. The caprock overlies the porous saline reservoir and prevents migration of CO2 upwards out of the reservoir. As such, the primary focus of this research is to test the effectiveness of caprock as a seal or barrier to fluid migration under representative conditions of a geological storage site. Additionally, a secondary focus is the assessment of the rock thermal properties and geomechanical modeling of CO2 injection. This is because thermally induced stress changes resulting from the injection of relatively cold CO2 can lead to the creation of leakage paths (e.g., formation fracturing or reactivation of existing discontinuities). The study area of this research is the proposed CO2 injection location of Project Pioneer (TransAlta) in Alberta. The caprock and storage reservoir in the study area are the Calmar and Nisku Formations, respectively. An experimental setup was developed to measure the permeability of intact and fractured caprock samples exposed to CO2-rich brine under representative temperature and pressure conditions of the injection site. The objective of determining the permeability of fractured caprock samples exposed to CO2-rich brine was to examine how caprock seal effectiveness may evolve over time in the presence of fractures which either preexisted or are generated during CO2 injection. The outcomes were used to assess the collective effects of chemical and physical processes that could lead to caprock leakage. Geomechanical modeling was conducted in this work to investigate injection-induced stress changes and to see whether their effects (deformation) within the storage reservoir are observed on the ground surface. The models incorporate the thermal, geomechanical and geometrical parameters of the saline reservoir and surrounding rocks. The permeability of intact samples of the Calmar Formation (primary seal/caprock) were measured as 0.3 nd (0.3·10-21 m2), and measured permeability of fractured caprock samples ranged between 10 to 40 µd (10·10-18 to 40·10-18 m2). The intact rock permeability is very low, hence, the rate of leakage would be very low (7.4·10-7 m3s-1). Potential leakage rates could be up to four orders of magnitude higher if the caprock is fractured from base to top. The geomechanical deformation model predicted that CO2 injection in the Nisku zone is not likely to cause any significant surface heave (< 2 mm), and it likely too small to be measured effectively using standard surface deformation monitoring techniques. Numerical modeling conducted by a research collaborator using results generated in this research suggests that thermally induced fracturing may occur at the study site if the injection rate is not carefully chosen

Aviation Demand and Economic Growth in the Czech Republic: Cointegration Estimation and Causality Analysis

The main purpose of the paper is to empirically examine the aviation-led growth hypothesis for the Czech Republic by testing causality between aviation and economic growth. We resort to econometric tests such as unit root tests and test of cointegration purposed by Johansen (1988). Fully Modified OLS, Dynamic OLS and Conical Cointegration Regression are used to estimate the cointegration equation for time span of 42 years from 1970 to 2012. Empirical results reveal the existence of cointegration between aviation demand and economic growth. Graphic methods such as Cholesky impulse response function (both accumulated and non-accumulated) and variance decomposition have also been applied to render the analysis rigorous. The positive contribution of aviation demand to economic growth is similar in all three estimation techniques of cointegration equation. Finally, Granger causality test is also applied to find the direction of causal relationship. Findings help in lime-lighting the importance of aviation industry in economic growth for a developing country like the Czech Republic

Calendar Anomalies in Stock Market: A Case of KSE 100 Index

This paper aims to investigate the calendar anomalies in Karachi Stock exchange by using KSE 100 index during the period of 2008 to 2012. The study examined the existence of week days, weekend and monthly seasonal anomalies. These calendar effects are examined by applying different statistical techniques. First of all series of daily and monthly returns were calculated. Then mean and standard deviation of daily and monthly returns were calculated. The values of mean and standard deviation have rejected the first two null hypothesis and accepted the third one. The results provide an evidence for the existence of calendar anomalies at KSE 100 index. The results showed that there is significant difference among the returns of days of the week, and Friday has highest mean average return which makes it confirm that weekend effect exists at KSE. Finally monthly anomaly in stock returns is also present because there is highest positive return in the month of March.     Keywords. Stock Market, Anomalies, weekday effect, weekend effect, monthly effect, Return

Hidden migration, livelihoods, identities and citizenship : Malawians in the city of Durban.

Thesis (Ph.D)-University of KwaZulu-Natal, Westville, 2004.This thesis is an investigation into the undocumented migration of Malawians to the city of Durban, and the influences on their livelihoods, identities and continued links to Malawi. In this context the thesis raises the issue of migration and citizenship. In the past Malawians were involved in contract migration system tightly controlled by the mining industry and the state, and in which their freedom of movement and association was circumscribed. This thesis argues that there is a new, emerging new form of migration, which may be termed transnational migration that has taken root since the early 1990s. It involves a web of links and networks created by transmigrants between Malawi and Durban. For a variety of reasons this transnational migration pattern is less visible, and largely hidden from the official gaze of the state. The reasons for migrating to Durban are mainly, through not exclusively economic ones, that is, about creating a livelihood, or multiple livelihoods. Malawian migrants become enmeshed in a series of livelihood itineraries as part of the chain of migration from towns and villages en route to, and in Durban. In pursuing their livelihood itineraries they begin to use their networks and other resources such as their ethnic and religious identities, family and friendship ties, nationality, accumulated experiences, skills and entrepreneurship to insert themselves in the city, and in the process, seek, find or create work in both the formal and informal sectors of the local economy. In this context they develop a sense of belonging to and being part of the city and begin to institutionalise their presence, contributing in many ways, both socially and economically to the city. The thesis argues that their presence, practices, dispositions and accomplishments in the city of Durban, and continued links to Malawi raise pertinent issues around the question of citizenship and migration
